Aligos Therapeutics, Inc. is a clinical-stage biopharmaceutical company dedicated to developing innovative treatments for significant unmet medical needs in both viral and liver diseases. Key candidates in its pipeline include ALG-010133, an s-antigen transport-inhibiting oligonucleotide polymer, which is currently undergoing Phase Ib clinical trials for chronic hepatitis B (CHB). Another asset for CHB, ALG-000184, a capsid assembly modulator, is progressing through Phase I clinical trials. Additionally, Aligos is advancing ALG-020572, an antisense oligonucleotide designed to stop HBsAg translation and secretion. Its portfolio also features siRNA drug candidates, including ALG-125755, ALG-125097, and ALG-125819, which have demonstrated potent capabilities in inhibiting HBsAg release from HBV-infected cells. For non-alcoholic steatohepatitis (NASH), the company is developing ALG-055009, a small molecule THR-ß agonist, now in Phase 1a/1b studies. Aligos has also forged several strategic alliances. These include licensing and collaboration with Luxna Biotech Co., Ltd. for HBV genome-targeting oligonucleotides, a partnership with Emory University for HBV capsid assembly modulator technology, an agreement with Katholieke Universiteit Leuven for the development of coronavirus protease inhibitors, and a deal with Merck to research and develop NASH-focused oligonucleotides. Established in 2018, Aligos Therapeutics is headquartered in South San Francisco, California.
Aligos Therapeutics Announces First Participant Dosed in the Phase 1 Study of its Potentially Best-in-Class Antisense Oligonucleotide ALG-170675 by its Partner Amoytop in China
Aligos Therapeutics and partner Xiamen Amoytop Biotech dosed the first participant in a Phase 1 study of ALG-170675, an antisense oligonucleotide targeting chronic HBV infection.
The study in China will assess single and multiple ascending doses in healthy volunteers before advancing to a cohort of HBV patients in Q4 2026.
ALG-170675 is designed as a next-generation therapy with improved activity and potentially reduced toxicity compared to GSK-836.
